writematrix for multiple csv files

Hello,

Essnetially I am attempting to achieve the following:

writematrix (PhaseAve{i, 1}, 'INTL_i.csv')

but I am unsure what the proper formatting is such that the file renames each i-th iteration.

I have utilized the following code to break out unique file names for each iteration, but now I am not sure how to reference that file name that corresponds to the i-th iteration. The first section succeeds in naming the files however the code gets stuck on the second section so I think that is where my formatting errors lie.

%%%% naming each file
i = 1: length(a);
BaseName='INTL_';
 for k=1:875
 FileName=[BaseName,num2str(k), '.csv'];
 end
 
%%%% writing to each file

 while i <= a 
     
 writematrix(PhaseAve{iii,1},FileName) 
end 

I know this is probably super basic...and I may not be explaining it well. Thanks for any advice in advance.

This is a long-form illustration of the result I am trying to achieve:

writematrix (PhaseAve{1,1},'INTL_1.csv')
writematrix (PhaseAve{2,1},'INTL_2.csv')
writematrix (PhaseAve{3,1},'INTL_3.csv')
writematrix (PhaseAve{4,1},'INTL_4.csv')
writematrix (PhaseAve{5,1},'INTL_5.csv')
writematrix (PhaseAve{6,1},'INTL_6.csv')
writematrix (PhaseAve{7,1},'INTL_7.csv')
writematrix (PhaseAve{8,1},'INTL_8.csv')
writematrix (PhaseAve{9,1},'INTL_9.csv')
writematrix (PhaseAve{10,1},'INTL_10.csv')
%through 
writematrix (PhaseAve{875, 1}, 'INTL_875.csv')
